North Sea's Hidden Crater Revealed: 160-Meter Asteroid Triggered 330-Foot Tsunami

Researchers confirm the Silverpit Crater beneath the southern North Sea was formed by a hypervelocity asteroid or comet about 43–46 million years ago. Using advanced seismic imaging and rock samples with shocked minerals, scientists show a ~160-meter-wide impactor struck at a shallow angle, producing a 1.5-kilometer-high curtain of rock and water that collapsed into a tsunami over 330 feet tall. The finding resolves a two-decade-long debate and places Silverpit among Earth's rare, well-preserved underwater impact craters.

Ancient North Sea Impact Fueled a 100-Metre Tsunami, Scientists Confirm

New evidence confirms the Silverpit Crater beneath the North Sea was formed by a ~160-meter asteroid at ~15 km/s in the middle Eocene (43–46 million years ago), generating a tsunami over 100 meters high within minutes.

Ancient North Sea asteroid sparked a colossal 100-meter tsunami

Researchers confirm that the Silverpit Crater beneath the North Sea was formed by a 160-meter-wide asteroid about 43–46 million years ago, triggering a tsunami over 100 meters tall and blasting a 1.5-km-high plume of rock and water. Using advanced seismic imaging and analyses of shocked minerals, the study resolves the crater’s origin as an asteroid impact and highlights the rare preservation of an oceanic impact site.

Ancient North Sea asteroid crash unleashed a 100m tsunami, study says

New seismic data and rock fragments confirm the Silverpit feature beneath the southern North Sea is an impact crater formed by a ~160-meter asteroid striking at a shallow angle about 43–46 million years ago, which generated a tsunami over 100 meters high. The findings resolve a long-running debate and place Silverpit among Earth's rare preserved submerged craters, alongside Chicxulub and Nadir.
